• Must have experienced =1 severe respiratory exacerbation requiring treatment with systemic corticosteroids or hospitalization or treatment in ED/urgent care within 12 months prior to the screening visit or must be receiving chronic stable low-dose OCS per above criteria

Key Exclusion Criteria:

• Weight less than 30.0 kilograms

• Current smoker or e-cigarette user, cessation of smoking or e-cigarette use within 6 months prior to randomization, or >=10 pack-years smoking history

• Post-bronchodilator FEV1 <30% predicted normal at screening

• Respiratory exacerbation requiring systemic corticosteroids within 4 weeks prior to screening and between screening and baseline visit (for patients on daily or alternate day OCS, exacerbation requiring at least double the maintenance dose of corticosteroids)

• Upper or lower respiratory tract infection within the 4 weeks prior to screening (visit 1) or between the screening and randomization visits

• Significant chronic pulmonary disease other than asthma complicated with ABPA (eg, physician-diagnosed bronchiectasis due to a condition other than ABPA; cystic fibrosis; sarcoidosis; interstitial lung disease not due to ABPA; chronic obstructive pulmonary disease [COPD] not due to ABPA; hypereosinophilic syndrome; etc), a diagnosed pulmonary or systemic disease associated with elevated peripheral eosinophil counts

• Diagnosis or suspected diagnosis of eosinophilic granulomatosis with polyangiitis (EGPA) (also called Churg-Strauss Syndrome)

NOTE: Other protocol defined inclusion / exclusion criteria applies.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change from baseline in pre-bronchodilator forced expiratory volume in 1 second (FEV1) compared to placebo		At Week 24
Secondary	Annualized rate of severe respiratory exacerbations	Defined as new onset of symptoms or clinical worsening of respiratory symptoms requiring systemic corticosteroid treatment for =3 consecutive days; for patients who are on maintenance systemic corticosteroids, at least double the dose of maintenance systemic corticosteroids for =3 consecutive days (with or without antibiotic therapy if indicated)	Over the 24 to 52 Week Treatment Period
Secondary	Annualized rate of ABPA-related exacerbations	Defined as severe respiratory exacerbations (as defined above) that are associated with a doubling of serum total Immunoglobulin E (IgE) from the prior pre-exacerbation value.	Over the 24 to 52 Week Treatment Period
Secondary	Annualized rate of severe respiratory exacerbations requiring either hospitalization or observation for >24 hours in an ED/urgent care facility		Over the 24 to 52 Week Treatment Period
Secondary	Change from baseline in Asthma Control Questionnaire (ACQ)-5	ACQ is completed by patient to measure both the adequacy of asthma control and change in asthma control, which occurs either spontaneously or as a result of treatment. The ACQ-5 score is the mean of the first 5 questions, between 0 (totally controlled) and 6 (severely uncontrolled). A higher score indicates lower asthma control. Patients with a score below 1.0 reflect adequately controlled asthma and patients with scores above 1.0 reflect inadequately controlled asthma. The optimal cut-point score of 1.50 should be used to be confident that a patient has inadequately controlled asthma.	Over the 24 to 52 Week Treatment Period
Secondary	Change from baseline in St. George's Respiratory Questionnaire (SGRQ) total score	SGRQ will be completed by the patient to measure and quantify health status in adult patients with chronic airflow limitation. Total score ranges from 0 to 100. Scores by dimension are calculated for three domains: Symptoms, Activity, and Impacts (Psychosocial). Lower score indicates better Quality of Life (QoL).	Over the 24 to 52 Week Treatment Period
Secondary	Percentage of participants achieving a reduction in the SGRQ score of 4 points or greater from baseline	SGRQ will be completed by the patient to measure and quantify health status in adult patients with chronic airflow limitation. Total score ranges from 0 to 100. Scores by dimension are calculated for three domains: Symptoms, Activity, and Impacts (Psychosocial). Lower score indicates better Quality of Life (QoL).	Up to 52 Weeks
Secondary	Percent change from baseline in total IgE in serum		Over the 24 to 52 Week Treatment Period
Secondary	Percent change from baseline in A fumigatus-specific IgE in serum		Over the 24 to 52 Week Treatment Period
Secondary	Percent change from baseline in fractional exhaled nitric oxide (FeNO)		Over the 24 to 52 Week Treatment Period
Secondary	Absolute change from baseline in FeNO		Over the 24 to 52 Week Treatment Period
Secondary	Incidence of treatment-emergent adverse events (TEAEs) from baseline		Through the end of the 52 Week Treatment Period
Secondary	Incidence of treatment-emergent anti-drug antibody (ADA) responses and titer over time		Up to 64 Weeks
Secondary	Concentrations of functional dupilumab in serum by treatment regimen		Up to 64 Weeks
